Not on the TR6.  Some TR4's vented the crankcase to the air cleaners but 
the TR6 Evap Control System is totally independent of the air cleaners.  The 
charcoal canister feeds directly into the venturis in the carbs.

Why they care about air cleaners is beyond me.  Maybe their actuarial 
tables show that cars with no mods or certain mods are less risk than cars with 
other certain mods.  Or maybe they are just throwing darts at the wall.  
Insurance companies work in mysterious ways.  But they always seem to be 
profitable.
